20100128181 | Seam Based Scaling of Video Content - Methods and systems are provided for processing video data. In an embodiment, a method of scaling video data includes scaling one frame based on at least one seam of pixels of the one frame. The seam of pixels is selected based at least on information derived from at least one of: a previous frame and metadata relating to the one frame. In an embodiment, a method of processing video data includes determining whether a frame is to be scaled based on at least one seam of pixels based on at least one of information derived from the frame or metadata relating to the frame. The at least one seam of pixels is selected based at least on an energy associated with each pixel of the at least one seam of pixels. | 05-27-2010 |
20100218207 | METHOD AND APPARATUS TO DETECT PREVIEW OF ENCRYPTED CONTENT - A method and apparatus detects a presence of a change in encryption status of video information, such as a preview, in a video stream. The method and apparatus issues notification information such as through a visual user interface, audibly or in any other suitable manner, that new content, such as a pay per view video information, is either available or unavailable based on the detection of a change in encryption status of the video information. An interactive and automated technique is provided to inform a user while, for example, the user is watching a display device, that a preview of content is now available or that a previously available preview has now changed and is now encrypted and therefore a user must order the previewed content before an expiration period occurs. In this fashion, a user is automatically notified that a free preview is available, while watching television and a broadcaster may increase revenues since preview information is more readily detected and presented to potential customers. | 08-26-2010 |
20100251307 | Systems and Methods for Processing Program Content and Information in a Video Broadcast - Embodiments of the present invention significantly decrease the processing requirements as well as the cost of digital television receivers. In an embodiment, processing requirements of both hardware and software components in digital television receivers are lowered by generating the channel map without regard to channel map information present in a Virtual Channel Table (VCT). In another embodiment, significant recurring portions of an ATSC signal can be neglected with no processing power, cost, and time spent thereon. In another embodiment, processing typically used to process channel map information contained in the VCT portion of the ATSC signal is freed and may instead be used to process other information, thereby enabling further enhancements and features in digital television services. | 09-30-2010 |
20110019978 | METHOD AND SYSTEM FOR PVR ON INTERNET ENABLED TELEVISIONS (TVS) - A media playback device may be operable to determine whether replacement media content corresponding to at least a portion of a received broadcast media stream is available during reception of the broadcast media stream from one or more broadcast sources. At least some of the replacement media content may then be retrieved when personal video recording (PVR) operations are requested during play of the received broadcast media stream, to enable seamless performance of the requested PVR operations using at least a portion of the retrieved replacement media content. Exemplary PVR operations may comprise pausing, fast forwarding, and/or rewinding. The replacement media content may be retrieved from a plurality of local and/or remote replacement servers. Availability of replacement media content, from remote replacement servers, may be determined based on programming data in said broadcast media stream, routing information provided by a broadcast source, and/or by inquiry via one or more cataloguing servers. | 01-27-2011 |
20110169930 | EYEWEAR WITH TIME SHARED VIEWING SUPPORTING DELIVERY OF DIFFERING CONTENT TO MULTIPLE VIEWERS - Systems and methods are provided in which eyewear with time shared viewing is capable of supporting delivery of differing content to multiple viewers/users. The content that is delivered to each viewer includes a respective frame sequence that is displayed on a screen. The frame sequences are mixed when they are displayed on the screen. A lens assembly may be used by each viewer to view the frame sequence that is delivered to that viewer. For instance, a first lens assembly may pass a first frame sequence but not frame sequences other than the first frame sequence. A second lens assembly may pass a second frame sequence but not frame sequences other than the second frame sequence, and so on. The content that is delivered to a viewer may depend on a maturity of the viewer (e.g., whether the viewer's maturity is less than a maturity threshold). | 07-14-2011 |
20120013798 | METHOD AND SYSTEM FOR ACHIEVING BETTER PICTURE QUALITY IN VARIOUS ZOOM MODES - A method and system are provided in which a video image may be scaled from a first to a second video format. The scaling may be a non-uniform scaling such as an anamorphic scaling. When panning associated with the scaled video image is detected, one or more end portions of a current frame of the scaled video image may be adjusted, the adjustment being based on one or more frames of the scaled video image that are previous to the current frame. The adjustment may result from combining information from the corresponding end portion of previous frames with the information of the current frame. One or more end portions that are opposite to the ones adjusted may also be adjusted based on one or more frames of the scaled video image that are subsequent to the current frame. The panning detected may be horizontal, vertical, or a combination thereof. | 01-19-2012 |
20120013807 | METHOD AND APPARATUS FOR FAST SOURCE SWITCHING AND/OR AUTOMATIC SOURCE SWITCHING - A method and system are provided in which a processor may perform fast source switching and/or automatic source switching by keeping active the signals from multiple sources. The processor may determine which received video signals are locked-in within a front-end portion of the processor. A video signal may be locked-in when a demodulator is locked to a carrier in the video signal or when a decoder is programmed to decode the video signal. During operation, the processor may switch from processing a current video signal to processing a video signal selected from those determined to be locked-in. The processor may maintain active a portion of a back-end portion of the processor to handle the switch from the current video signal to the selected video signal. The processor may switch to process between video signals when a predetermined content and/or metadata is detected within one of the video signals. | 01-19-2012 |
20120019726 | METHOD AND SYSTEM FOR APPLYING CONTENT-BASED PICTURE QUALITY PROFILES - A method and system are provided in which a video channel is selected from multiple video channels in a video processor. A picture quality profile associated with a content of the selected video channel is received by the video processor to modify a value of one or more picture quality control parameters utilized by the video processor that are mapped to a user level setting. Metadata associated with the content of the selected video channel may be determined and communicated to a server. The server may utilize the metadata to determine a picture quality profile for the video processor. In some instances, environmental conditions associated with a television or display device may be measured and communicated to the server to determine the picture quality profile. For example, the measured environmental conditions may comprise one or more of an ambient light, a sound, a motion, and a temperature measurement. | 01-26-2012 |
